Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Can you please confirm if you are referring to your tags taxonomy? If you wish to modify its global or default meta, you can find it in your WordPress Dashboard > Rank Math > Titles & Meta > Posts: Tags.
If it seems that I am still missing something, kindly explain the issue in detail so we can provide a solution accordingly.
Looking forward to helping you.
